We present a new approach to consider and include both the perturbative and the non-perturbative contributions to the multiplicities of gluon and quark jets. Thanks to this new method, we have included for the first time new contributions to these quantities obtaining next-to-next-to-leading-logarithmic resummed formulas. Our analytic expressions depend on two non-perturbative parameters with...

Regular data taking with the CMD-3 detector at the VEPP-2000 electron-positron collider in Novosibirsk is underway since 2010. The luminosity up to 10**31 cm-2s-1 has been reached at the energy 2E=2 GeV, and another order of magnitude will be achieved after construction of the new positron source.
The already collected physical data sample corresponds to about 60 inversed picobarns of...

Experiment HERMES at DESY collected a large set of DIS data using the 27.6 GeV polarized
electron/positron beam and various, polarized and unpolarized, gaseous targets.
In this talk an overview of the results obtained in the experiment will be presented.

The upgraded VES detector has recently collected the highest
world statistics of the reaction pi- Be -> pi- pi0 pi0 Be
- about 14 000 000 events. This allows us to perform mass
independent partial wave analysis in 10 non-equidistant
intervals of squared momentum transfer t' in the region
0 < t' < 1 GeV^2.
The second stage of the analysis is the model-dependent
fit...

The inclusive production of the meson resonances $\rho^{0}(770)$, $f_0(980)$,
$f_2(1270)$, $K^{*+}(892)$ in neutrino-nucleon interactions has been
studied with the NOMAD detector. The detector was exposed to the wide band neutrino beam
generated by 450-GeV protons at CERN SPS. For the first time the $f_{0}(980)$
meson is observed in neutrino interactions. The presence of $f_{2}(1270)$ in...
